Tin Cup (1996) - 36 mistakes

Factual error: After Roy's first round in the US Open, there is a NASCAR race on TV. The race is the Brickyard 400, which is run in August, showed during the US Open, which is played in June.

Continuity: When Molly comes for her first golf lesson, Costner takes the last bite of his hot dog. In the next scene, he still has some of the hotdog left.

Visible crew/equipment: When Roy is first practising at the U.S. Open you can see cue cards in Romeo's sunglasses a few times.

Continuity: During the press conference at the U.S. Open where Roy begins to list the companies who are sponsoring him, he says that one of them is "Woody's Smokehouse" when the patch on his jacket says "Wally's Smokehouse".

Continuity: When Roy and Romeo buy back his golf clubs from the pawn shop, the towel on the gold bag keeps changing positions as they are walking and talking.

Audio problem: At the end of the movie when Roy finally makes the shot, The scene cuts to Molly on the side and she has her mouth open as she's screaming, but you hear her voice saying "I LOVE YOU".

Continuity: When Roy is talking to Romeo about winning the U.S. Open he is seen with a glass of milk in his hand in one scene and in the next the glass in on the table in front of him.

Factual error: When Roy is giving Molly her first golf lesson, she is using a driver, the hardest club to hit. Any golf professional would have a student start with a short iron.

Revealing: In the scene where Romeo and Roy snap all the clubs other than the 7-iron, Roy drops his golf ball onto the grass. However, when he hits the ball, a white tee can be seen travelling up towards the top left of the screen. The tee can easily be seen but is much clearer in slow motion.

Continuity: When Molly goes to see Roy when he is wearing all that golfing equipment, when they go to sit down at the table Roy can be seen taking off the blue arm band and when the camera pans back for a wider shot, he is seen taking it off again.

Continuity: When Roy is talking to Molly after their therapy session, the magazine Roy is reading disappears in one shot and then it's back in the next.

Continuity: In the scene where Molly comes to visit Roy in his winnebago, her hairstyle changes from minute to minute.

Continuity: During Molly's first golf lesson we see Roy about to show her how to swing the club. Right from the moment after which she takes her shot to where we see him take his, his hair changes styles during all of the different shots. This is particularly noticeable with his fringe.

Continuity: When Molly goes to see Roy when he is wearing all of the golfing equipment, they walk outside and Roy pushes the lid of the ballcap he is wearing to the side. The camera angle changes and you now see the lid is facing straight back.

Continuity: After Dave takes his first shot on the final hole, he is seen walking and you can see that his glove is tucked in his back pocket. The camera angle changes to a front view and you see him taking off his glove and tucking it in his back pocket again.

Continuity: Right after the spotter points out to Roy where his ball is in the woods, not only does the spotter disappear, but Roy is seen moving a large leaf that was not even near the ball in the first shot of the scene.

Continuity: In the scene where Costner is playing Johnson in the final round, we see both of them lining up their putts. Costner is swinging the grip of the putter from side to side in front of his face. When we see him through Rene Russo's periscope, he is not moving the club at all. The shot cuts back to Costner, and he is swinging the club again.

Continuity: The first lesson Molly has with Roy, it's already dusk, and when they go outside, it's dark. At the end of the lesson, Roy says "Same Time Next Week?" and Mollie says "Okay."  But then in the next lesson Mollie complains that he is late.   But when he does show up for that late lesson, it appears to be in the late afternoon, not even close to dusk.

Continuity: During the scene in the final round where Roy and David hit their balls onto a green, there are a couple of mistakes (one mistake has already been noted in this scene - the mistake where Roy is swinging his putter from side to side etc). Firstly, as they all walk up to the green, Roy's ball (which should be quite close to the hole) is not on the green. Secondly, when Dave misses his putt, look at Romeo. He is standing to the right of Roy, but in the immediate next shot he is on Roy's left.

Continuity: When Roy goes to see Molly at her office we see him about to ask Molly out. During this scene Roy's hair style constantly changes. His fringe is messy and sticking up when the camera faces him from Molly's view; and flat and tidy when the camera is at the opposite angle.
